RAILROAD-BUFFER CONSTRUCTION.

Application filed June 1, l1926, Serial No. 113,915, and in GermanyNovember 13, 1925.

rlhis invention relates to a railroad-buimodied construction of Figure 3it is not ter oi the thrust triangle type which is simple inconstruction and efficient in operation and comprises the use oi' woodenbrake members in connection ber of a thrust triangle.

The invention is illustrated on the accompanying drawing.

Figure l is a side elevation of one embodiment ot the improved butlerconstruction, some parts being broken away, and Figure 2 is a partialsectional View ot one of the buffer thrust triangles. Figure 3 is apartial sectional view similar to Figure 2 of a modiiied construction.'

In Figures 1 and 2 a buffer carrying rail is designated by a. is afarther rail7 forming an element of the triangle base. The side elementsot the thrust triangles are indicated by c. cl designates a wooden brakebeam or brake block connected to rail o by bolts e having coiled springsf put thereon which tend to yieldingly press the brake beam Z againstthe track rails head a. The illustrated arrangement of the one thrusttriangle is also provided for the thrust triangle of the other rail,both triangles as usually being connected together by a buffer beam g.

The application of the buffer base as an clement of a slide constructionresults in a particularly simple construction whereas he connection ofthis metal piece with a wooden brake block ensures proper braking etiectby irictional engagement ot sliding parts and certain elastic qualitiesfavorable 'for the transmission of thrust.

.lt is not essential for the invention that the rails a on which thebuiier is mounted, are the rails on which the vehicle or train to bestopped by the buiier is running; the butter may be mounted on sepa-rateflanged beams in parallel relation to the track rails. it will beunderstood that these beams need not to be raiis and likewise it is notindispensable that the base element of the buffer consists ot a normalrail; any other suitably flanged beam may be used which by its flange isin engagement with the tia-nge ot a carrying beam.

in the butter construction of kFigures 1 and 2 it is particularly thestrong frictional engagement between the wooden beam d and the buttercarrying rail a whereon the etliciency ot the construction on slidingdisplacement o the buer depends. In the with the base mem! so much thisfunction but a certain resiliency of the wood'whereon the eiiiciency ofthe construction depends, may it be in connection with a slidingarrangement of the buffer, may it be in connection with'a buffer ot' thestationary type. In' Figure 3 the ret erence letter L designates theside elements ot a. thrust triangle7 z' are claw members rigidly securedthereto and iirmly gripping the rail or metallic beam 7c on which thebuiier is mounted. Z is a wooden beam firmly connected with the bufferand in tight contact with the upper surface of the beam 7c. Gn impactot' a car or train on the buiter the exerted shock tends to tilt thebutter so as to press down the buiier end remote from the impacting car.Under the eiiect of this tilting tendency the wooden beam Z at the saidend of the buffer remote from the car is somewhat compressed and it hasbeen found that such compression ot' an intermediate member ot asomewhat elastic and not absolutely rigid nature such as wood materiallyaids in the taking up of stress, so that with the insertion of such awooden or the like beam the buer is adapted to take up much more violentshocks than without same.

What I claim is v 1. In a railroad butter Vconstruction a thrusttriangle mount/ed on a flanged beam, said thrustA triangle having a baseelement comprising a flanged metallic beam engaging with its iiange theflange of the supporting beam, said metallic base element ot the thrusttriangle connected with a non-metallic friction member contacting withthe supporting beam, the triangle adapted to slide along the supportingbeam under rictional engagement of said non-metallic member and thesupporting beam..

2. In a railroad buffer construction a thrust triangle mounted on arail, said thrust triangle having a base element comprising a i'langedbeam engaging with its flange the head of the supporting rail, saidflanged beam connected with a non-metallic member contacting with thehead of the supporting rail, the triangle adapted to slide along thesupporting rail under frictional engagement of said non-metallic memberand the head of said supporting rail.

3. In a railroad buiier construction a thrust triangle mounted on arail, said thrust triangle having a base element comprising a railsection engaging with its head portion the headvl of the supportingrail, said rail section of the triangle base being connected with aWooden member rietionally engaging the lateral Surface' of thesupporting rail' head opposite that side of the rail head which is inengagement with the triangle base rail, the triangle adapted to slidealong the supporting rail.

4.111 a railroad buffer Construction a thrust triangle mounted on arail, said thrust triangle having a base element comprising a railsection engaging with its head portion the' head on the supporting rail,said rail section of the triangle base being yieldingly connected with aWooden member frictionally engaging the lateral surface of thesupporting rail head opposite that side' of the rail head Which is inengagement With the triangle base rail, the triangle adapted to slidealongv the supporting' rail.

5. In a Irailroad buffer construction a thrust triangle mounted on arail, Said thrust triangle having a base member comprising a Wooden beampositioned along the upper surface of the head of the supporting railand metallic connectors maintaining the triangle in lifting preventingengagement With the supporting rail,

In testimony whereof, I aiiix my sig-na ture.
